Well I'm finally getting around to breaking in my ACS bolt. Dang the spring is much more tense than I envisioned it. Why teh hell make the spring so heavy is beyond me. Almost seems to defeat the purpose of having one in there in the first place -

Anyways I throw my N2 tank on and put one of my home made barrel swabs in the feed neck and shoot it. For some reason I'm expecting it to recock. Well duh me.........it doesn't. I'm thinking like well crap imma have to shoot this thing and recock it like 500 or so times before the spring is broken in? NO WAY! So I remove the bolt again and lay the front on a flat surface then take the dowel rod end of the swab and start pushing up and down on the metal piece at the back of the bolt that's connected to the spring. Once again I say I'm not gonna sit here and do this for a half hour. Dang, what to do? -

Then I start thinking about some people leaving their markers cocked while not using them and the spring gets weak and will not get to velocity so they need to buy a spring kit for another heavy spring. Ah ha......voila! If I compress this spring in this bolt in the same manner, it's going to do the same thing as what I've been trying to do. It'll save me propellant and time from trying it the other ways I mentioned. Thing is finding something that will fit in the slot and be the right width to compress the spring as far as possible. So I'm like searching all over my apartment finding nothing that flips the bill and hit the silverware drawer in the kitchen, Aha, the perfect insert! My trusty mechanical can opener that I never used lol. I just used the dowel rod to push down on the metal spring thingy and inserted the can opener -

Now I don't have to sit and waste time by shooting and recocking this thing or fiddling with the up and down dowel rod technique. I'm sure this will do a much better job as the other ways as well. I'll prolly leave it this way for a day or two and it'll deffinitely be well broken in. I'll check it occasionally in between. Now I have extra time to make a thread here sharing this with everybody else lol.

Great Idea !!! *puts in favorites* ... now this is what im gonna link everyone that asks this question to :D ... Clever Creative Wisdomizing thinking Dragon ;)

Edit: What gun is it that your currently using that uses the ACS bolt ??

If that works I'll be pissed...no offense...it's a great idea...but I was always taught springs only wear down from the actual cycling of the spring. being left in a compressed or uncompressed state is supposed to have little no impact. Thats why I, you, the police can leave your semi auto pistol cocked and never have to worry about spring failure...

With that said...I must of cycled mine by hand 500 times?Dear god I hope this works for you...my fingers do too! (maybe light gauge springs are different....)

If this works...You're a genius! and I better go check the springs in my pistol.........

Cycling the spring only imposes a momentary stress on the spring. Leaving it compressed for a lengthy time leaves a continual stress on the spring. Which would be more prone to weakening or deforming the spring shorter? As stated, I got the idea from people leaving their markers cocked when not in use. This is a no-no. Leaving a firearm in a continual compressed state will have its toll as well but firearm springs are a much thicker gauge than any paintball marker. If you shoot your marker 500 times it will leave less stress on the spring than leaving it in a continual compressed state IMHO. It's hardened spring steel but not impervious to stress -

Thanks for the props guys. Sharing ideas and info is the main reason for having these forums. I was pretty green when I got here but just picked up a few things on the way - ;)

I'm wondering why it didn't recock in the first place? When I broke my Jambolt in, all I did was put the barrel swab down the breech and rip like hell for about 5 minutes. It recocked every single time.

Oh, well! Interesting - I wonder how many people here have actually seen one of those old can openers? Wait, I wonder how many actually know how to use one of them, LOL!

Let us know how it works.

those can openers arn't that old ... i actually have one right now ... my parents don't feel the need to spend money on an electric can opener when they can use me to spin the little knob a few dozen times ...

Then again .. now a days there's those quick open ones with the tabs ... pretty much like a coke can ..

hmm, i found a way to do it without a can opener, i dont have one like that, and its my old acs bolt anyways, but it does not compress as good as dragons, so this is a alternative, i did it to all three of mine, except the rear cocking one, i stuck under my bed between the frame and the floor

sorry bout the last pic, i am not very patient, lol, there were three pics

Nice killerpinecone......just showz-ta-go-ya.....creativity is easily transmitted and can esculate at any moment - ;)

I checked it out today and I must say that there is a noticable difference. The spring is defiantly easier to compress. Still not as easy as I envisioned it as being for some reason. I envisioned it being more like what Vik mentioned. Where it would stop on the ball but still recock. Seems Kingman had more the idea of stopping on the ball but not recocking. A little testing may be in line here. I will try it like this and if not satisfactory, leave it for another day or two. Patience and trial and error are good virtues - :cool:

Well, you don't want it to compress too easily or it may compress on firing, when the bolt is released from inertia.

Strikefirst, if you keep a firearm cocked in your household you are an absolute retard. I'm sorry, but that's pure STUPIDITY, unless you are planning to have to use it very soon. The springs wont fail, but if that firearm were to fall and it's an old style hammer without modern protections, it will most likely go off. Common sense: unload the gun, seperate the magazines and ammo and firearm, and leave it with a gun lock through the firearm's breech.

Good idea Drago, this thread'll make it easier on all of us with having to answer those "how do I make my ACS stop chopping?" questions. Mad props! :)

What I'm saying is that if the spring is TOO weak, the ACS spring will compress as the bolt moves forwards when the sear is released. The bolt not being forwards when firing=not so great, air goes up the feed and out the barrel...

This is similar to the person who modded their ACS for o-rings, the o-rings caused to much drag as I had predicted and caused the front of the bolt to not move forwards the entire way. The same thing would occur if the spring was not stiff enough to hold the front of the bolt forwards.

The spring will still be stiff enough to keep it from not going forward.

I have an aluminum ACS with o-rings and never had a problem. Also, all 3 of our ACS bolts (2 delrin, 1 aluminum, all Kingman) are pretty broke in know and I have never had a spring too weak problem....

If you oil/lube the o-rings you shouldn't have a problem.... :rolleyes:

The person that used a machinists lathe had a derlin ACS bolt ... prolonged periods of times with oil will make it swell ... don't think it would work ... ??

If you do it right, they wont. You only need to lubricate the o-rings, not the delrin. ;)

DRAGON

07-16-2006, 09:43 PM

Well I tried it out today and it worked pretty good. The only real prob I can see with this bolt is blowby. When it got down to the last 4 or 5 balls they were shooting back up into the hopper big time. I mean shot up so much I lost sight of the ball for a split second, not good. There was a couple breaks. I use ultra evil which has a very brittle shell so I kind of expected it with this HP marker. Once my MR is LP'd and has a lighter push and main spring, I think things will get better. I had at least 10 stops out of 1000 balls and it didn't seem to promote any chopping. When I get ahold of these Spyder's, things always get better as I progressively mod them. This one's getting a female Palmer's, rocket valve, light main spring and some more home mods. That's another thing that will alleviate chopping, a lighter main spring -

well you don't use your head...its a service model XD pistol...it has 5 safetys built in...in can't fire by being dropped, banged our thrown...it also has 2 safetys required to be engaged a grip safety and a trigger safety...oh and as far as a gun lock you ignorant person its in a touchpad lock box thats allows for 2 second entry. So you person not thinking before you go spouting off about how other people do things...maybe you should get the rest of the information and why else would someone keep a pistol? P r o t e c t i o n...We've had problems with immigrants making sexual comments to my wife and 4 year old AND caught someone trying to break in...twice...SO...dip wad why dont you shut your friggin mouth and get the facts BEFORE you pop off with ignorant garbage.

Oh wait I also forgot to mention my conceal and carry permit...but once again you probably already new that didn't you!

I had the same problem, you just have position the dowel the right way in the feed neck.. I found that chap-stick tubes work great, better than swabs, I think..

Then again ... as it moves through the body ... i'd think the oil would spread ... causing the derlin to touch it at some point ...

Meh i give up though :p

Just bought a Derlin ACS bolt today, so I will try and use the idea of just keeping the sping compressed rather than dry firing it. I hope it works out, and thanks for the idea. :)
